Not sure, but if it's still the original HG on my '97 V6 motor at 370,000K am I driving on borrowed time ? There are currently no signs of a problem however. Just wondering.
Exactly, being with that amount of KM if it does go I would consider finding a good used motor. Also I see you're from NB, everything I've seen that comes from out there is rusty rusty rusty. So you may be on borrowed time as it is.
